Abstract
We compute the critical temperature of Bose-Einstein condensation in dilute three-dimensional homogeneous Bose gases. Our method involves the models of spatial permutations and should be exact to lowest order in the scattering length of the particle interactions. We find that the change in the critical temperature, Delta T-c/T-c((0)), behaves as ca rho(1/3) with c = -2.33. This contradicts the current consensus among physicists.
